FASTENING--INSERTING MACHINE.

Application. filed .April 19, 1924. Serial No. 707,767.

This invention relates to machines for inserting fastenings and is herein illustrated as embodied in a machine which forms staples from continuous materiahsueh as wire, aud then drives the staples into the work. y

lt is` au object of theinvention to provide a machine of this type which will be simple in construction, accurate in its adjustments to provide fastenings of different lengths, and particularly etilective in the forn'iation and insertion of fastenings exactly suited to the varying` cliaracteristics of the work operated upon.

in the attainment of this object and in acf cordance with one feature of the invention;

the wire feeding means of the illustrated machine yieldingly operated to feed the wire stock against an abutment which is adjustable by means which also controls the wire feeding means so that the length of wire for a fastening may be accurately varied in accordance with the desired lengthof fastening. Preferably. and as shown, the means which controls the wire feeding means and the abutment also effects and. controls adjustment of the wire cutting means.

Another feature of the invent-ion comprises the combination of a wire cutting means and a movable abutment disposed on opposite sides of a fastening forming member and arrangerI to be simultaneously adjusted rectilinearly toward and `from each other so that the two prongs or 'legs of a staple fastening may be changed to an equal extent whenever the lengths of the fastenings are varied in accordance with changes in the thickness of the work. ot the invention the operator may predetermine the length of faste-nings to suit the 'work through the operation of a manually controlled lever. rlhe invention contemplates also, and as illustrated includes, means controlled by the work itself for determining the length of fastening to be inserted at any given point. Y

in order that each fastening may be provided with a straight cross-bar, arovision is made for the co-operation of a die'with one of the fastening forming members. This illustrated arrangement necessitates the transferring of thestaple from forming .position to driving position and improved means is provided for preventing dispacement of the fastening during this transln one'illustrated embodiment fer movement. Preferably, and as shown, a prolongation of the inside fasteningy forming member serves as a means for preventing displacement of the fastening with respect to the outside forming member during its transfer by said mem-ber. f

The invention contemplates also the provision of improved means for wiping the marginal portion of an upper of a Shoe over the marginal portionof a sole where the machine is employed in securing the upper to a lip or rib on a sole assembled with a last; an important function of the wiping means being to effect' a smoothing down of the upper to provide a completely adequate seat for the welt during welting operations on the shoe. As illustrated, the-wiper member constitutes also the lower wall of the nozzle which supports the. fastening and the fastening driver. the wiper operating7 in thev manner described, prior to the insertion of the fastening which is guided along the' upper surface of the wiper and into the work after the latter has been smoothed down at the extreme end of the wiper.

Other features of the invention and novel combinations of parts will be described in the detailed specification and pointed out in the appended claims.

In the illustrated machine, fastenings are formed from wire stock w supported on a reel. 20 (Figs. L and 2) from which it is fed through the operation off. feed rolls 22, 24, a tube 2G bein` preferably provided for guiding the wire from the feed rolls to the cutg ting mechanism comprising' cutters 28 and 8O (Figt l0) which operate to sever lengths of wire from .which fastenings may be formed. By reference to Figs. 2 and 8 more particularly it will be observed that the wire feed mechanism comprises means for intern'iittently rotating` the feed rolls 22, 24 always in the `same direction and for varyingthe length or` amount of wire fed by the rolls. In the illustrative construction. the lower feed roll 22 is mount-ed upon a shaft 3G supported in bearings in the frame of the machine and having iixedly secured thereto a gea-r wheel 38 arranged to be constantly in mesh with a corresponding gear wheel 40 which is secured to rotate with the upper roll 2411s() that the upper roll is positively driven from the lower. roll. Preferably7 the upper roll 24 and its gear 40 are mounted upon a stub shaft 42 carried by a lever 44 pivotally mount-ed at 4G on the frameof the machine and having` its other end 47 perforated for the passage of a bolt 48, the lower end of which passes also the length. of fastening to be through the-rounded end 50 of a projection secured fixedly to the frame ofthe machine. Between the upper surface of the end 47 and a nut 52 on the end of the bolt 48 is a spring 54 which operatesto press the roll 24 against the lower roll 22. Secured to the lower end of the bolt 48 cam member 56 having a handle 58; lhen the cam projections of the cam member 56 are engaged in correspondingly shaped notches in the member 50, as shown in Fig'. 2, the tension on the spring 54. is relaxed so that the end-of the wire` may be readily introduced between the rolls,.22, 24; Upon returning' the handle' 58 through 90O back to the position indicated in Fig. 4 the bolt 48 is moved downwardly, thereby putt-ing increased tension on the spring' 54 and causing the rolls 221a 24 to grip the wire with sufficient firmness to feed the same. At the other end of the relatively short shaft 86 is a ratchet wheel GO' secured thereto, said ratchet wheel arranged to be operatedy upon by a pawl or set ofpawls 62 (Figs. 2 and carried at the end of an arm 64 loosely mounted on af shaft (t's-upported bythe frame of the machine in such manner as to be inV horizontal alineinent with the shaft 36. For operating the pawls 62 yield- I ingly in a direction to cause` feedingl movements of the feed rolls 22, 24 there is proi vided an anni: 68 rigidly secu-red tothe shaft G6 and carrying` at its lower endv a curved link member 70l which passes loosely through a perforation in the end ofa projection Z2 extending laterally from the arm 64 which carries the pawls. Between lthe perforated endof the projection 72 and the lock nuts 74 on the endof the link 7() is a spring-76 which is so tensioned as to cause prompt movement of the pawls (52' and ratchet wheels 60 upon rockingl of the shaft (S6 whereby the feed rolls 22, 24 are given theirproper feedingmovement.V lf, nowevcr. t-he end of the wire beine' fed by the feed rolls 22, 24 encounters an.` yObstruction the spring` 76 will yield sufficiently to prevent any damage-tothe wire or Vto the parts which contact therewith. Carried by the projections- 72 is a pair of. leaf springs 78 which press upon the pawlswto hold them in contact witlnthe ratchet wheel GOso that theyG will engage properly with the teeth thereof. In order to vary the throw of the ratchet wheel'GO and thus make provision for changu ing the lengths of thev fastenings7 there is provided al controller in the form of a curved shield member 8() whichextends aroundwa portion of the periphery of the ratchet wheel'GO. Itwill be clear thatvif'the shield 80 be moved so asv te intercept the pawls G2 inpart of the path of movement of the latter that'. the operative stroke ofthe pawls willy be lessened in accordance with the amount that the ends of thepawls ride over the surface of the shield. In theconstruc tion shown the shield or controller member 80is-mounted upon a sleeve 82 rotatable on the shaft 66 and provided, on a portion of its surfacerwith gear teeth 84.l adapted to mesh with the teeth ofv a rack- SG-carried by ablocki87 mounted upon a slide bar 88. t will be clear from an inspection of Fig. 2 that movement of theslide bar 88 will be followed by movement of the shield in adirection'to-cover or uncover portions of the 1atchet wheel 60 thereby varyingthe length of the effective portion of the stroke vof the pawls 62.. For rock-ing"- the shaft 66 there are provided connections leading' back to; cam 90 on the shaft 92 (Figs. l, 4 and 7) 'the -said'connections comprising a lever 94 loosely mounted on shaft 96 and having a roll 98 for engagement with thecam 90,v the upper end of the lever being pivotally connected by a link 100 with an arm 102liXedly secured to the end of the shaft 66. By means of a spring 104 (Fig. 7) the lever 94 is held against the cam 90 so that the lever is rocked through the operation of vthe cam whereby a corresponding rocking movement is transmitted to the shaft Gt'and this movew ment in turn, through the pawl. and ratchet mechanism described, transformed into an intermittent rotation of the rolls 22, 24 in one direction to cause feeding of the wire in predetermined amounts at regularly recurring intervals.

As before stated, the means for cutting the wire stock into lengths for Afastenings comprises the cutters 28 and 80 (Figs. 9 and 10) l cutter' 28 being the stationary cutter and 30 being the cutter movable at the time of the severing of a fastening length from the wire stoclrf It Will be observed that the cutting face of the cutter 28 is at the end of a wire guidevvay in the body portion of the cutter member and that the cutter is a vertical blade-like member adapted to pass across the end faceof the cutter 28 to sever the Wire length from the wire stock. In the construction shown the cutter has a flange vand rib portion 108 which assists in strengthening the cutter blade and' holding it firmly in place in a cutter support 110. When it is desired to change the lengthy of the fastening the cutters 28 and 30 must be adjusted in the direction toward or away from an abutment 111 which serves as a stop to locate the end ofthe Wire stock as the latter is fed intoy position prior to each cutting operation. The abutment co-operates with the feed rolls 2,2, 24 in determining the exact length of wire fed at each operation of the feed rolls, the end of the Wire coming against the abutment serving to check any tendency to overthrow movement of the feed rolls. Hence, the cutter 28 is mounted in a block 112 which is in turn secured to a slide member 114', having at its other end, ratchet teeth 116 adapted to be engaged by teeth 118 on the lower end of a sleeve member 120, so that upon rot-ation of the sleeve member the slide 114 is caused to move in one direction or the other to adjust the critter' 28. This same movement of the slide 114 also moves the other cutter 30 in the same direction and to the same extent since the cutter support or block which supports the cutter 30 is mounted by a tongue and groove connection shown at 122 in the slide 114 so as to partake of the lateral movement of the slide 114. A cap or cover is provided to cover the cutter slides. In order that the cutter block 110 may move laterally along with the cutter 28 and still maintain itsconnection With an operating bar 124,

the block 110 is provided Wit-h a hardened block'126 preferably to receive slidably the stud 128 extendinglaterally from the side of the operating bar 124. At the same time that the slide 114 is moved to the right in Fig. 10 a block 130 which carries the abutment 111 is moved tothe left through the operation of v the teeth 118 on the sleeve 120 in engagement with ratchet teeth 132- on the block 130; Thus, when the cutters 28 and 30 are moved to the right inA Fig. 10 to shorten the fastening length of vvire the abutment 111 is moved at the same time toward the cutters, so to 'shorten the fastening length of wireequally may be, and preferably is, a part of, or integral with, the bar 88, heretofore described as employed for the purpose of varying the length of Wire fed through control of the shield 80 (Fig. 2). From an inspection of Figs. 2, 9 and 10 it will be observed that movement of the bar 88 in a direction to rotate the sleeve. 120 in a clockwise direction, Will cause a shorter length of Wire to be fed, by interposing more of the shield or controller 80 in the pat-h of the pawls 62,'at the Asame time that the cutters 28 and 30 and the abutment 111 are caused to approach each' other to cut off a shorter fastening having legs of equal length. On the other hand, movement of the bar88 in a direction to cause l countercloclnvise movement of the sleeve 120 will causo shifting of thecutters and the abutment 111 in a direction away from each other at the same time that the shield or controller 80 is moved to uncover a l'argerpart of the ratchet wheel 60 to the Laction of the pawls 62, thus providing for a tening required by the work. The connec- ,tions between the treadle and the slide bar 88 comprise, in the construction shown, a linl g or rod (-Figs. 1 andA 9) the lower end of which is adapted to be pivoted to the treadle 141, its upper end being also pivoted, at 142, to the end of a lever 144 loosely mounted on a shaft 146 mounted in bearings in the frame of the machine. Fixed on the frame Fixed to the segment rack 150, or integral therewith, is a bar 154 having in its ends, respectively,-adjustable bolts 156,A 158 adapted to contact with shoulders 160, 162 on a 'trame part or casing of the mach-ine to limit rocking movement of the bar 154 and, tliere'lore, of the segment rack 150. Plate 148 is provided with notches 164 in the upper arm portion thereof for engagement selectively with one end 166 of al spring 168, the other end of which is connected to the lever 144 normally to hold the lever in elevated position.. lWhen the lever is in the position shown in 1 and 9 the wire feeding and wire cutting means are in position to feed and cut a short fastening.` lf the treadle be depressed until the bolt 158 contacts with the seat 162 then the slide 88 will be moved to the left, through connections comprising the rack 150, and a longer fastening length of wire will be fed and cutofll to make a staple fastening with longer prongs.

It j ireferrec'l, av lra'iid lever may be provided so that kthe yoperator may adjust the wire cutters. and the wire feeding means through a' lever shifted by hand. ln fact, this hand lever may be employed inthe same machine with the treadle controlled means so that the operator may have his choice of means under his control for lengthening or shortening the fastening. Conveniently, the handle control is shown as comprising a hand lever 18() (Fig. 12) secured to the upper end of the sleeve 120 so that the sleeve 120 is operated directly to effect adjustniients of the cutters and of the abutn'ient 111 with respect to each other, the slide bar 88 being operated from the sleeve instead of operatingthe sleeve as when the treadle is used.- In other words, the slide bar 88 has the same raclr and pin-ion connection to the upper end of the sleeve 120 as that shown in Fig. 10', the only difference being that the sleeve 120 becomes the source of power for the bar 88 when the hand lever 180 is employed by the operator. Hence, when the hand lever 180 is shifted by the operator the wire feed is controlled by the bar 88 in the manner already described. Gne advantage of the hand lever 180 over the trea'dle con-trol is that the handle 180 may be more readily adjusted to a. larger number of positions. In the construction shown in Fig. 12. a positioning bar 190 is secured to the, frame of the machine and is so shaped that its outer edge 192 is concentric with the center of the sleeve 120. At each end ofthe positioning bar 190 is a gage block 194 each of which Lerares j s lmaybe secured in adjusted position to in;

the limits of the throw of the khandle lever 180, thereby ,atY the same time determining the i'ninimuin and maximum lengths of'fastonings. .This isl what is secured by the treadle controlled mechanism lthrough the adjustable screw boltsy 156, 158 (Fig. 9). ln addition, the hand lever 180 may-loe adjustedvat intermediate points through the operation of asprin-g pressed bolt 20() mounted on the lower side of the handle and adapted to engage selectivelyin a series of notches 2O2Aso that a fastening intermediate between the minimum and maxim-uni fasteuingmay he secured according to the judgnient of the operator.

The fastening forming anddriving devices, in the construction shown, comprise an inside former `210 9 and 10) which is 'lixed in position, beingv securely fastened by having a portiony thereof 212 bent and lirmly screwed to a projecting partvv or bracket 214 which is ,secured to, or integral with, the head portion of the machine frame (Figs.4 7 and 9). The lower part of the bracket 214 provi-des, in the constructionshown the upper stationary plate 216 of the nose 217 of the fastening inserting mechanism'. Inv other words, this plate 216 contains a gu-idewaym218 Viorthe fastening and for the driver (Figs.A 8 to .11 inclusive), the lower wall of the guideway being formedY by a movable member 220 which also operates as a wiper member, as will be hereinafter described. For co-operation with the inside former 21() informingaf staple fastening there is provided, in the construction shown, an outside former 222 comprising two relatively short plates 224, 226 each having` a vgroove on its innersurface in which the wire is receivedas it is bent over the inside former 210. These plates 224, 226 are secured upon the lower lend of a former carrier 228 which is reciprocable vertically in the operating bar 124 for a purpose thatv will be hereinafter described. Then the operating bar 124 is moved to the right in Figs. 9 and 10 the outside formerv 222 is caused to approach the inside former 210 to engage the length of wire w and press it against the adjacent vertical edge of the inside former 210 just at the instant the cutters 28 and 30 sever this piece from the main body of the wire stock. A plate 229 serves as a cover to confine the length of wire being cutfofl thereby assisting in directing the end of the wire across the edge of the inside former and into contact with the abutment v111. Continuing in its movement the outside former bends the piece of wire around the inside former 210. At the'y termination of this forward movement a die member 230 contacts with the cross bar of the staple pressing it firmly against the vertical end face of the inside vber 220. as iust described.

lower end of former 210, thus making a straight cross bar on the fastening. Preferably, and as shown, the die member 230 is carried at the lower end of a plate 232 which is secured to a casing or housing member 234' at the forward end of the operating slide 124. Following the formation of the fastening the outside former 222 is moved downward.- ly as its carrier 228 is depressed to its lowest point so as to bring the plates 224, 226 into straddling engagement with respect to trie member 220 (Fig. 11) whereby the staple carried in the grooves in the plates 224, 226 is located on the upper surface of the member 220 below the lower end of the prolongation 211`of inside former 210 and in line with a staple fastening driver 240. It will be observed that the inside former serves to keep the staple fastening in the outside former during its transfer Afrom forming to driving position. The means for reciprocating the carrier 228 comprises an operating means having a yielding connection therein so that the outside former members 224, 226 will be sure to be brought into proper operative relation to themem- Referring to lifigs. 1 and 9 it will be seen thatthe carrier 228 is provided with a .forked portion 250 in which is `located a block 252 having `truunions 254 for pivoting ,the block in the forked portion 250. Passing slidably through the block 252 is a bolt 256, the which is forked to receive the end of af lever 258 to which the boltis pivoted. Between the upper surface ofthe block 252 and look nuts 260 on the upper end of the bolt is a spring 262 which is compressed at the end of the downward movement of the carrier 228 so as to insure that the staple fastening in the outside former will be carried into engagement with the upper surface of the memberv 220 (Fig. 11). In order that the carrier228 .may be moved upwardly to a predetermined position so as to locate the grooves in the outside former plate 224, 226 in proper alinement with the wire w there is provided onr the .bolt 256'a pair of lock nuts 264 to engage the under side of the block 252, the `said lock nuts being adjustable so that the uppermost position of the carrier 228 ,may be determined during the setting up of the'vmachine .and adjusted as may be required by wearing of the parts of the operating means. Lever 258 is pivoted as at 268 (Figs. land 4) upon a projection orbracket fixedly secured to the frame of the machine, the said `pivot point being at a point intermediate between the ends of thelever, and the other end carrying pivotally a` block 270 (Fig. r1) which is slidabletransversely in a slot in the verticall slide memberv 272 which carries at its lower end a'roll. 274 for Contact with'.

a cam 276 carried by thefshaft 92, the slide member 272 audits roll 2 74 being constantly pressed against the cam by -a spring 278 (Fig. 4). It the co-operation 'of the spring 278 and the cam 276 the lever 258 will be rocked to cause reeiprocation of the carrier 228 with the outside former 222. As before stated', the outside former 222 is reciprocated towardy and from the inside former 210 by the operating bar 124 which is mounted for horizontal reciprocation in guideways in the frame of the machine, the means'for reciprocating the operator bar comprising rack teeth 290 (Figs. 1 and 9)V secured on a projection 292 from the lower side of the bar, the teeth beingfin mesh with teeth 294 on` a segmental rack bar 296 at the vupper end is also operated through connections to the block 110 comprising the block 126 and stud. 128 already described. Important features of the fastening forming means not claimedv herein will be Vfound described and claimed Vin applicants eopending application Serial No. 653.291, filed July 23, 19,23.

For operatingthe fastening driver 240' there is providedy a driver bar 310 carrying a block 312 (Figs. 1 and 6) adapt-ed tol be held in Contact with a cam 314. fixed to the shaft 92, by means of a spring pressed lever 316 adapted to exert pressure on the driver bar 310 through a. link' 318. When' the block 312i drops ofi' the end 320 (Fig. 6) ofthe cam 314 the driver bar 310 is suddenly forced to the right in Fig. 1 by the-spring which operates the lever 316. whereby the fastening driver 240 is suddenly impelled, as by a hammer blow, to drive the fastening through the nose 21.7 and into the work which is clamped between the end of the nose and a work supporting and clamping member 324. In Fig. 6 the lines 90a. 276 and 304a indicate the paths of the centers of the rolls 98. 274 and 302 respectively. y The member 324. Areferred to above` as `work supporting and clamping member, is conveniently of a curved hook shape'sc that it may becarriedby va. bar or other support 326 at one side of the plane of fastening insertion and still constitute no obstruct-ion to l theproper positioning of the work with rewill be understood that through.
